Parkinson's disease (PD) is characterized by the progressive loss of the dopaminergic neurons in the substantia nigra and a severe decrease in dopamine in the striatum. A promising approach to the gene therapy of PD is intrastriatal expression of enzymes in the biosynthetic pathway for dopamine. Tyrosine hydroxylase (TH) catalyzes the synthesis of L-dopa,(More)
The B19 parvovirus is responsible for at least three human diseases. The virus was successfully propagated in suspension cultures of human erythroid bone marrow from patients with hemolytic anemias; release of newly synthesized virus into the supernatants of infected cultures was observed. This culture system allowed study at a molecular level of events(More)
This fully-integrated direct conversion/very-low-intermediate-frequency (VLIF) transceiver contains dual LNAs, dual quadra-ture mixers, baseband filtering, receive (RX) and transmit (TX) VCOs, and TX buffers. The IC is part of a highly integrated low-cost, GSM/GPRS platform that consists of five separate ICs. A block diagram of the transceiver is(More)
In two children with acute lymphocytic leukaemia in whom severe anaemia developed, serum samples collected over 9-12 months showed high concentrations of B19 parvovirus, the aertiological agent of fifth disease. In one patient, anaemia recurred with the reappearance of virus in serum; in the other, the anaemia persisted. Smears of bone marrow aspirates(More)
Glial cell line-derived neurotrophic factor (GDNF) is known as a potent neurotrophic factor for dopaminergic neurons. Since adeno-associated virus (AAV) vector is a suitable vehicle for gene transfer into neurons, rat E14 mesencephalic cells were transduced with an AAV vector expressing GDNF. When compared with mock transduction, a larger number of(More)
